Microplastics (MP) are the subject of intensive medical research, but little is yet known about their effects on the immune system. A study led by the Medical University of Vienna now shows that tiny particles of polyethylene ...

Astronomers from the George Washington University (GWU) in Washington, DC, and elsewhere have employed NASA's Chandra X-ray spacecraft to observe a pulsar wind nebula inside a supernova remnant known as CTA 1. Results of ...

Even though sugars are often framed as simple sources of energy, they also serve as structurally complex and functionally diverse molecules that mediate interactions between organisms. Among these, β-1,2-glucans, which are ...

Researchers have discovered a new way that brain plasticity is controlled in early life, offering insight into the little-understood phenomenon of critical-period closure. In the months or years after birth, critical periods ...

Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football (soccer ball) being kicked ...

Patients in London have received a pioneering new gene editing therapy that lowers "bad" cholesterol after a single infusion, as part of a study involving UCL scientists.

When a 10-kilometer asteroid struck Earth 66 million years ago, the planet was plunged into darkness—and about 75% of species vanished, including marine life. Now, a new study reveals that the planetary effects from the impact ...

By stacking transistors on top of one another, rather than laying them side by side on a flat chip, many electronic engineers are hopeful that vast amounts of computing power could be packed into tiny spaces, all while cutting ...

More than 1,000 years ago, Panama elites were buried together with translucent green stones long suspected to be emeralds. However, scientific analysis confirming the suspicion has never been conducted. Now, scientists have ...

A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line.

Few creatures inspire as much universal dislike as ticks. Though small, these parasites have an enormous impact on human and animal health. Each year, ticks spread viruses and bacteria that infect people, livestock, wildlife, ...

Many soybean farmers use seeds treated with fungicides to ward off disease, but the profits from these increased yields might not offset the cost of the treatment in most cases, according to a study published in Scientific ...
